运行rails服务器时没有"jcode"gem

Question

当我尝试运行'rails server'时,它给我一个错误,说它找不到'jcode',我认为jcode是一个默认的ruby lib.你们有什么线索关于什么事情发生？

Answer 1

听起来像你正在使用的库没有为Ruby 1.9更新.

Ruby> = 1.9没有jcode,一个处理日语(EUC/SJIS)字符串的模块,因为它本身支持unicode.

您可能希望看到更新版本的库可用,否则您可以查看源代码并找到它需要jcode的位置,并将其替换为

require 'jcode' if RUBY_VERSION < '1.9'

Answer 2

我们应该检查gdata gem文件下的lib文件夹.

添加此行:

require 'jcode' if RUBY_VERSION < '1.9'

在lib/gdata.rb文件中.
